Registering Debian Clients
This section contains information about registering Salt clients running Debian operating systems.
Debian is supported for Salt clients only. Traditional clients are not supported.
Bootstrapping can be used with Debian clients for performing initial state runs, and for profile updates.

Bootstrapping can be used with Debian clients for performing initial state runs, and for profile updates.
1. Prepare to Register
Some preparation is required before you can register Debian clients to the SUSE Manager Server:
-
Ensure DNS is correctly configured and provides an entry for the client. Alternatively, you can configure the
/etc/hosts
files on both the SUSE Manager Server and the client with the appropriate entries. -
The client must have the date and time synchronized with the SUSE Manager Server before registration.
2. Add Software Channels
Before you can register Debian clients to your SUSE Manager Server, you need to add the required software channels, and synchronize them.
In the following section, descriptions often default to the |
The products you need for this procedure are:
OS Version | Product Name |
---|---|
Debian 11 |
Debian 11 |
Debian 12 |
Debian 12 |
-
In the SUSE Manager Web UI, navigate to
. -
Locate the appropriate products for your client operating system and architecture using the search bar, and check the appropriate product. This will automatically check all mandatory channels. Also all recommended channels are checked as long as the
include recommended
toggle is turned on. Click the arrow to see the complete list of related products, and ensure that any extra products you require are checked. -
Click Add Products and wait until the products have finished synchronizing.
Alternatively, you can add channels at the command prompt. The channels you need for this procedure are:
OS Version | Product Name |
---|---|
Debian 11 |
debian-11-pool-amd64 |
Debian 12 |
debian-12-pool-amd64 |
-
At the command prompt on the SUSE Manager Server, as root, use the
mgr-sync
command to add the appropriate channels:mgr-sync add channel <channel_label_1> mgr-sync add channel <channel_label_2> mgr-sync add channel <channel_label_n>
-
Synchronization starts automatically. If you want to synchronize the channels manually, use:
mgr-sync sync --with-children <channel_name>
-
Ensure the synchronization is complete before continuing.
3. Check Synchronization Status
-
In the SUSE Manager Web UI, navigate to
and select theProducts
tab. This dialog displays a completion bar for each product when they are being synchronized. -
Alternatively, you can navigate to
, then click the channel associated to the repository. Navigate to theRepositories
tab, then clickSync
and checkSync Status
.
-
At the command prompt on the SUSE Manager Server, as root, use the
tail
command to check the synchronization log file:tail -f /var/log/rhn/reposync/<channel-label>.log
-
Each child channel generates its own log during the synchronization progress. You need to check all the base and child channel log files to be sure that the synchronization is complete.
Debian channels can be very large. Synchronization can sometimes take several hours. |
4. Manage GPG Keys
Clients use GPG keys to check the authenticity of software packages before they are installed. Only trusted software can be installed on clients.
Trusting a GPG key is important for security on clients. It is the task of the administrator to decide which keys are needed and can be trusted. A software channel cannot be assigned to a client when the GPG key is not trusted. |
For more information about GPG keys, see GPG Keys.
Debian clients can require multiple GPG keys to be installed. |
When synchronizing third-party Debian repositories, you will need to import the appropriate GPG key on the server. If the GPG key is missing, synchronization will fail.
For Debian repositories, only the metadata is signed. Therefore importing a GPG key for the software channel is not needed. Packages will not be re-signed by Uyuni.
To see which GPG keys are already imported to SUSE Manager Server, run the following command:
sudo gpg --homedir /var/lib/spacewalk/gpgdir --list-keys
To import a new GPG key, use the --import
parameter:
sudo gpg --homedir /var/lib/spacewalk/gpgdir --import <filename>.gpg
5. Root Access
The root user on Debian is disabled by default for SSH access.
To be able to onboard using a regular user, you need to edit the sudoers
file.
-
On the client, edit the
sudoers
file:sudo visudo
Grant
sudo
access to the user by adding this line at the end of thesudoers
file. Replace<user>
with the name of the user that is bootstrapping the client in the Web UI:<user> ALL=NOPASSWD: /usr/bin/python, /usr/bin/python2, /usr/bin/python3, /var/tmp/venv-salt-minion/bin/python
This procedure grants root access without requiring a password, which is required for registering the client.
When the client is successfully installed it runs with root privileges, so the access is no longer required.
We recommend that you remove the line from the |
6. Register Clients
To register your clients, you need a bootstrap repository. By default, bootstrap repositories are automatically created, and regenerated daily for all synchronized products. You can manually create the bootstrap repository from the command prompt, using this command:
mgr-create-bootstrap-repo
